Question

the area of a rhombus is equal to the area of a triangle whose base and the corressponding altitude are 24.8 cm and 16.5 cm respectively. if one of the diagonals of the rhombus is 22cm, find the length of the other diagonal.

Answer 1

Area if Traingle=1/2*base*height
=1/2*24.8*16.5
=12.4*16.5
=204.6cm^2

Area of Traingle=Area of Rhombus
Area of Rhombus=1/2*d1*d2
204.6=1/2*22*d2
204.6=11*d2
204.6/11=d2
18.6=d2
